The glue is very "watery" and it does not stick right away. The label on the bottle says open work time is "10 - 15 minutes", which is not true. You would have to hold two pieces together and wait at least 30 minutes before the glue takes effect. This is particularly bad for me because I was trying to glue a wind-shield strip to my patio door: the strip keeps falling off because the glue is so slippery! Eventually I had to stand there and press the strip for more than 10 minutes, then I thought it worked. However, when I checked back later, the glue did solidify but the strip slipped down a bit and it was misaligned and wrinkled, and there was yellow glue knots everywhere! Sorry my patio door, I failed you!
